Major airlines will purchase many of the new aircrafts capable of carrying more than 500 passengers on transcontinental and transoceanic flights. These airlines currently rely on "hub and spoke" systems of routing, in which large planes, which can seat 400 people and are capable of transoceanic flight, fly into hubs that have runways sufficiently long to handle them. From there, passengers are dispatched to local airports on connecting flights on small planes. With takeoff and landing time slots almost completely booked at most hubs, and little new runway construction expected, airlines will want to expand the volume of passengers they can fly in a given time slot.

The argument above would be most weakened if which of the following were true?

A. The new 500 seat aircraft cost more per seat than existing aircraft

B. Air traffic control systems at most hub airports cannot handle any more flights per hour than they currently do.

C. The new 500 seat aircraft require boarding times substantially longer than those of existing aircraft

D. Small passenger aircraft, capable of efficient transcontinental and transoceanic flight and able to land on short runways, have come into service

E. Transoceanic air flights are currently running at near maximum capacity

Why not C? Argument is that buying 500 seater plane will be profitable provided airlines can fly more passenger in a given time slots, since they operate in a hub-spoke system they are bound by time slots at each hub. Hence if airlines cannot comply with that time slots of hub they will not be able to maximize the profit with 500 seater plane.

lets look at the options:

A. The new 500 seat aircraft cost more per seat than existing aircraftIrrelevant and out of scope. Hence out.B. Air traffic control systems at most hub airports cannot handle any more flights per hour than they currently doThis one would look very attractive. However, this is something that is already mentioned in the argument. Read the last sentence, With takeoff and landing time slots almost completely booked at most hubs, and little new runway construction expected. Its already given that the most slots are booked. Also, as a remedy, there is a new runway being setup. So this cannot weaken the argument. Hence out.C.

Small passenger aircraft, capable of efficient transcontinental and transoceanic flight and able to land on short runways, have come into serviceThis option weakens the argument. Our entire argument is based on the assumptions that there are no small aircrafts available that are efficient in making transcontinental and transoceanic flight. Because, if there are such aircrafts then the Airlines will buy these small aircrafts (instead of the bigger aircrafts) capable of making the flight and landing at the local airports directly. This would increase the airllines volume of passengers at a given time slot. HoldE. Transoceanic air flights are currently running at near maximum capacityThis does not weaken the conclusion in any way. Hence out

Premise 1: Major airlines will buy new airplanes that have capability of loading 500 passengers and flying over ocean (and continent)Premise 2: These new airplane rely on the "hub and spoke" system, in which the large airplane (400 pas) need enough long runways to take off and landingPremise 4: Hubs slots is full now

Conclusion: If major airlines want to operate new airlines, they have to expand current runways

A. The new 500 seat aircraft cost more per seat than existing aircraft => quite irrelevant, the air ticket cost more, mean that cost need to offset with the new constructions of runwaysB. Air traffic control systems at most hub airports cannot handle any more flights per hour than they currently do. => StrengthenC. The new 500 seat aircraft require boarding times substantially longer than those of existing aircraft => Strengthen. 500 seat airplanes need more boarding times, so expanding runways is necessaryD. Small passenger aircraft, capable of efficient transcontinental and transoceanic flight and able to land on short runways, have come into service => this one is not strong answer, but it is the most sentence that can attack the expanding runways plan. Small passenger aircraft come into service, companies do not need to buy large airplane and not need to expand runwaysE. Transoceanic air flights are currently running at near maximum capacity => Does not explain the new constructions is bad idea

There is no medium, transcontinental and transoceanic flights, to go to small air port .Hence if new flights can take more passenger in one go,then airlines can expand their business.Pre thinking:For weaken big fligts will not be able to land in the existing airport --Other way passenger can directly move to local airport/local town.

Well I think the reasoning using which I eliminated C is as below:

Fact : From the stem we understand that existing 400 seater planes are capable of transoceanic flight and fly into hubs that have runways sufficiently long to handle them. Conclusion or aim of the airlines: Airlines want to expand the volume of passengers they can fly in a given time slot.

Assumption: Within a given time slot, we do have a way to increase passengers using the new 500 seater,capable of transcontinental and transoceanic flights, and no other alternative.

We need to weaken the above assumption link.

When we look at option C i.e. The new 500 seat aircraft require boarding times substantially longer than those of existing aircraft, we do not have any idea about boarding times for existing 400 seater. Additionally, it might be the case that additional capacity of carrying 100 passenger might still help the airlines achieve the aim. In short, if an option has insufficient info then it will not weaken the conclusion most.

But looking at option D, we know that we do have an alternative to carry additional passengers within a given time slot, keeping in mind that additional runaway construction is unlikely. So this does weaken the conclusion most.

I am not an expert but hope this helps!!

Hope its clear

'Air traffic control systems at most hub airports cannot handle any more flights' is not equivalent to 'airports cannot handle any more flights'. I think you are confusing these two terms. You could add on a hundred runways but what it says is that the traffic control cannot handle any more flight. If there are 2 people working in air traffic control then they might not be able to handle the traffic no matter how many runways you add.

'But companies will replace their old fligts' -- it's not the airline companies who will replace the systems. Their willingness to expand wholly relies on the fact that other systems are the same. My point here is that if they add new planes to their fleet but the traffic control cannot manage the new flights then those airplanes will just be left idle in the hangars.

D is practical and efficient option.If I were a airline CEO, I would have chosen small aircraft which can land on other small airports.

Cheers!J

The conclusion: Major airlines will purchase many of the new aircrafts capable of carrying more than 500 passengers on transcontinental and transoceanic flights.

Given that all other options clearly don't look valid here is my take on C and D:

C. The new 500 seat aircraft require boarding times substantially longer than those of existing aircraft. Let's look at the line 'With takeoff and landing time slots almost completely booked at most hubs, and little new runway construction expected, airlines will want to expand the volume of passengers they can fly in a given time slot.'The words 'almost' and 'most' do not really give us a clear picture of how saturated the time slots are. eg. out of 10 hubs 7 may have their time slots almost completely booked but the remaining 3 may have enough to accomodate these new 500 seat aircraft with longer boarding times. This does not weaken the conclusion that major airlines will purchase many of the new aircrafts capable of carrying more than 500 passengers.

That being said, the argument assumes that, given the situation, the airlines will not want to consider any other option but to expand the volume of passengers they can fly in a given time slotwith the new 500 seat aircraft.There may be another option which is likely to help the airlines achieve their objectives better, weakening the statement thatMajor airlines will purchase many of the new aircrafts capable of carrying more than 500 passengers on transcontinental and transoceanic flights.

D. Small passenger aircraft, capable of efficient transcontinental and transoceanic flight and able to land on short runways, have come into service. This is an option which clearly is a better bet for the airlines given the current situation and hence, weakens the conclusion.

D is the correct option because Small Air-crafts will not be flying to hubs, where it is impossible to add more air crafts because of already full landing and take off time slots. Instead the Small aircrafts will be flying directly to the smaller domestic airports, which is the real final destination of travellers. Thus this weakens the airlines' plan

I think D is correct because the concern here is that big planes require longer runways, and according to option D if we have a plane which is capable of efficient transcontinental and transoceanic flight and able to land on short runways. The whole problem of "Hub and Spoke" system of routing itself will not come into picture and hence airlines would not want to purchase many of the new aircrafts capable of carrying more than 500 passengers on transcontinental and transoceanic flights. That's what i think should be logical explanation of option D. Any comments most welcome.

At the same time we are not provided any information on the landing and/or time requirements for the new small planes.

"Boarding times" in C insinuates that additional time will be required to accommodate these 500 person planes, and the argument premise states that take-off and landing time slots are maxed out - these three times may or may not impact each other and may or may not weaken the conclusion.

On the whole this isn't as airtight as weaken questions should be...

On second thought, as you've mentioned, hub and spoke would be removed from the equation, thereby removing the concern about times. Perhaps you're right, but I still feel that this isn't airtight.

Conclusion of the argument is -> airlines want to expand the volume of passengers they can fly in a given time slot by purchasing 500 seat aircraftsThe Reason being -> Takeoff and landing timeslots of the hubs in transoceanic flights being maxed out with no new plans for construction of runwaysSo, to weaken this argument we need to provide a reason not to buy the 500 seat aircrafts

A. The new 500 seat aircraft cost more per seat than existing aircraft.->Even thought technically this is a valid reason, it doesn't refer to the points in argument to come to this conclusion. Cost is out of Scope

B. Air traffic control systems at most hub airports cannot handle any more flights per hour than they currently do.-> In this case, having higher per capacity of aircrafts is better to serve more people. It increases the performance of both Hubs and Airlines. So, buy 500 seat Aircrafts

C. The new 500 seat aircraft require boarding times substantially longer than those of existing aircraft.-> The hubs are only used for dispatching of customers, so boarding time doesn't play a vital role here. Buying the 500 Seated Aircrafts does not hurt

D. Small passenger aircraft, capable of efficient transcontinental and transoceanic flight and able to land on short runways, have come into service.->In this case, better go with Small passenger aircrafts! Since they are transcontinental, the capacity of hubs doesn't matter as there is an alternate. They can land directly in local aircrafts instead of Hubs. Also, with the increase in the landing places, the volume of people they can serve should increase as well. So, don't purchase the 500 seat aircraft, but go with the small passenger aircrafts.

E. Transoceanic air flights are currently running at near maximum capacity. -> We are talking about flights here, and not the hubs. If the flights are reaching their maximum capacity, then buy the 500 seat aircrafts

I think the OA given is wrong. Here's my view:

Why D is wrong: It is mentioned that airlines are currently using hub and spoke model. That means, if they evenstart using new smaller planes, they'll still follow the old model and in the old model they'll need substantially more number of planes to carry same number of passangers as those carried by a larger plane. Sincw time slots are limited, the option of using smaller planes is wrong.

Why C is correct: This is because if new planes start taking more time to board, then airlines will nor have suffient flight numbers in the limited time slots they have. Their new planes would become useless in that case. Hence the best weakener against use of new planes.

Hi!

The argument above states that the airlines will purchase bigger planes to expand the volume of passengers they can fly in A GIVEN TIME SLOT.

Option C-How much ever more time it may take, it will always carry 25% more passengers at any given time slot.

Option D-The airlines use these large planes because they are capable of Transoceanic flights. They use the hub-spoke model because these large planes cannot land on these smaller runways.This option brings an alternative to their operation model by bringing new planes which are capable of efficient transcontinental and transoceanic flight and are able to land on short runways.

So, the answer is D.

Please let me know if you find some errors in the reasoning.
